JSR-303 (“Bean Validation”) ActionScript3 framework for form validation

validation framework is a specific adaptation of the JSR-303 (Bean Validation) specification to Flex: like its Java counterpart, it relies on validation annotations placed on bean properties and provides an engine API that lets you validate your forms without writing by hand a specific validator for each of your input fields

code generation tools provided by GraniteDS so that when you write your Java entity bean with validation annotations, they are automatically replicated in your ActionScript3 beans

problem with LCDS is mainly that it promotes a strict “client / server” architecture, with – roughly speaking – a heavy Flex client application connected to a server almost reduced to a database frontend

big majority of  these organizations use BlazeDS, a free and open-source subset of LCDS

need more advanced mechanisms than just Remoting start looking for open-source libraries to enable deeper integrations with the Java business layer, and GraniteDS is for sure the most popular project

“Flex Data Services” (now renamed to “Live Cycle Data Services”)

Flex Data Services seemed too “client-centric”

for GraniteDS users keeping their Java domain model and ActionScript3 domain model in sync via Gas3, the constraints are kept in sync

a couple of gotchas to be aware of

the constraint implementation is in the same class as the constraint declaration (not a problem in a dynamic language) @Pattern has a sightly different semantic because the regexp engine in Flex is a bit different. instead of the features provided by ConstraintValidatorContext, you can define a properties attribute in your constraints to make it belong to several sub-properties. not as flexible but good enough in many cases.

Known Causes:

First Steps:

dreaded errno 150:

The two key fields type and/or size is not an exact match

One of the key field that you are trying to reference does not have an index and/or is not a primary key

One or both of your tables is a MyISAM table

You have specified a cascade ON DELETE SET NULL, but the relevant key field is set to NOT NULL

Make sure that the Charset and Collate options are the same both at the table level as well as individual field level for the key columns

You have a default value (ie default=0) on your foreign key column

You have a syntax error in your ALTER statement or you have mistyped one of the field names in the relationship

The name of your foreign key exceeds the
